Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a precision parts storage box for storing precision parts used in electric products such as televisions, radios, videos and compact disc machines (CD machines).

[0002]

[Prior art]

 When transporting precision parts used in electric products such as TVs, radios, video recorders, and CD machines, they are generally housed in a transport box made of foamed-particle molding, which is an in-mold foam-molded product. The body is easily scraped or chipped by the stored items, and fine resin powder is easily generated. Since this resin powder interferes with precision parts, it is the current practice to wrap each part in a bag made of vinyl chloride film before it is stored in a box.

[0003]

[Problems to be solved by the device]

 Wrapping the contents one by one in a bag takes time and labor, the packaging cost is naturally high, and there is a problem that automation by a robot is difficult. If the box is made of in-mold foam molding with foamed particles, it cannot be finely shaped to match the shape of the parts to be stored, and it becomes a mere lattice frame, so the precision parts move due to vibration during transportation. There were always problems when it broke

Therefore, an object of the present invention is to eliminate the problem that resin powder is generated, while providing an article storage concave portion that can fit the shape of the precision parts to be stored, and close the body and lid. The purpose is to provide a precision parts storage box made of expanded polystyrene sheet that is firmly stopped when they are opened and is prevented from opening unintentionally due to wind or vibration during transportation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the precision parts storage box, which is a feature of the present invention, is made of foamed polystyrene sheet and has a body and a lid that are foldably connected by a hinge part. Is provided with an article storage recess that can be joined to each other when both are closed, and a fitting part that can be fitted in a state where at least a part of them are in surface contact.

[0006]

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 is a body, 2 is a lid, and both are integrally molded products made of expanded polystyrene sheet that are connected in a foldable manner by a hinge portion 3 that is thinner than other portions. The body 1 and the lid body 2 are formed with a large number of article accommodating recesses 4 and 5 that can be joined to each other, and the body 1 and the lid body 2 can be fitted into and removed from each other. , 7 are provided to form a precision parts storage box.

In the structure of this precision component storage box, one fitting portion 6 is formed in a hole and the other fitting portion 7 is formed in a protrusion, and the shape thereof is a triangle such as a triangle or a quadrangle. Therefore, it is necessary that at least parts 6a and 7a can exhibit the frictional action by surface contact. Further, it is preferable that the heights of the fitting portions 6 and 7 are 5 to 10 mm, and the portions (the above-mentioned portions 6a and 7a) that come into surface contact are parallel to the hinge portion 3. In the case of the illustrated embodiment, The fitting portions 6 and 7 are provided on the three sides of the body 1 and the lid 2 and in the center, respectively, and are considered so that the closed state of both can be determined. It is needless to say that the one fitting portion 6 may be a recessed portion, and the fitting portions 6 and 7 may be provided with concavities and convexities reversely.

The expanded polystyrene sheet is manufactured by extrusion molding, and a normal thermoforming means such as vacuum molding or pressure molding is used to manufacture the present precision component storage box from the sheet. An antistatic layer may be provided inside the lid 2 by applying an antistatic agent or laminating and bonding an antistatic agent-containing sheet. Furthermore, perforations may be provided in the hinge portion 3 to reduce the repulsive strength when the lid body is bent, and to improve the fittability of the components housed in the body 1 and the lid body 2, which is desirable. . In the figure, 8 is a ridge for reinforcement.

[0009]

[Effect of device]

 The present invention is as described above, and since it is made of expanded polystyrene sheet and there is no possibility that resin powder etc. will be generated, it is not necessary to wrap precision parts in a bag, and it is of course possible to reduce the cost by just that much. Therefore, the storage work can be automated. Also, since the article storage recess can be molded into a shape that fits into the precision parts to be stored, rattling during storage of the stored parts can be eliminated, and due to the presence of the fitting part, it can be closed. Its practical value is extremely great, as it eliminates the concern that the body and lid are opened carelessly.
